/* =====================================================================
   Tosconime — Netflix-style redesign layer (2026)
   Loaded AFTER style.css and BEFORE mobile-enhance.css.
   Reuses the existing "Aurora Duotone" tokens from style.css (:root).
   NO Netflix red — the "Netflix" here is STRUCTURE (billboard + rows +
   hover-card), never color. Everything stays on --accent / --accent-gradient.

   Sections:
     [A] LAYOUT — Billboard hero
     [B] LAYOUT — Rows as protagonists + hover-card
     [C] LAYOUT — "Explorar tudo" block + collapsible filters
     [D] EPISODES / SEASONS — season selector + episode tools
     [E] MOBILE — billboard/rows/filters/seasons breakpoints
   ===================================================================== */
